Re: Sound problem
Typically when you here a "pop" when you power on the radio it is a grounded out speaker (however you usually cant hear anything). Listen to each speaker (when turning it on) and see which one the pop is coming from. If it comes from all of them and you are not using a 4 ch. amplifier then I would start the diagnosis with the deck.
